[Bug] Cannot play a TS stream (TS sample reader not created)

[matthuisman]

Describe the problem

Tried in Kodi 21 and Kodi 22 with same issue

#EXT-X-STREAM-INF:BANDWIDTH=9077281,AVERAGE-BANDWIDTH=8614650,CODECS="avc1.640034,mp4a.40.2",RESOLUTION=1920x1080,FRAME-RATE=23.976,CLOSED-CAPTIONS=NONE

IA will fail to play the above manifest
FFMPEG plays it without issues

The above should work anywhere in the world

The lower quality stream is OK

the root of problem is not the warning "Cannot get the stream sample reader"
there is a problem in the mpegts demuxer where is not able to find the stream info in the packet
when it try to create the sample reader execute
TSReader::Initialize() -> TSReader::ReadPacket -> this last one fails, seem because for x reason is not able to find stream info
since then the sample readers is not created playback cant start due to no extradata extracted

@kodiai if i attach a TS package are you able to parse the packet and check for the problem?

Kodiai encountered an error

Kodiai hit its Claude usage limit

Claude Code returned an error result: You've hit your limit · resets 2am (UTC)

Kodiai cannot run another Claude review until the provider usage limit resets. Please try again after the reset time shown above.

@kodiai can you answer to my question on my previous comment?

[kodiai]

kodiai response

You're correct that this is a false positive. The initialization order is safe.

The actual call sequence:

(1) CDRMEngine::Initialize() (DrmEngine.cpp:155) calls CWVDecrypterA::Initialize() first, which:

• Sets ANDROID_SYSTEM global variable (WVDecrypter.cpp:35)
• Calls SetBaseClassName() (WVDecrypter.cpp:162)
• Creates the class loader (WVDecrypter.cpp:174)

(2) Only after Initialize() succeeds, CreateSingleSampleDecrypter() (WVDecrypter.cpp:64) is called from DrmEngine.cpp:236 or :432, which:

• Creates the CWVCdmAdapterA instance (WVDecrypter.cpp:79)
• The adapter constructor then creates the listeners (WVCdmAdapter.cpp:115, :126)

The listeners (CMediaDrmOnEventListener and CMediaDrmOnKeyStatusChangeListener) require access to xbmc_jnienv(), which depends on the ANDROID_SYSTEM global. Since Initialize() is always called before CreateSingleSampleDecrypter(), the JNI environment is guaranteed to be set up before the listeners are constructed.

Regarding JNIThread: The JNIThread (only compiled under #ifdef DRMTHREAD) has no relation to SetBaseClassName or listener initialization - it's just a worker thread for JNI operations and doesn't affect the initialization sequence.

Evidence:

• src/decrypters/DrmEngine.cpp:155 (Initialize called first)
• src/decrypters/DrmEngine.cpp:432 (CreateSingleSampleDecrypter called after)
• src/decrypters/widevineandroid/WVDecrypter.cpp:35, :162 (JNI setup in Initialize)
• src/decrypters/widevineandroid/WVCdmAdapter.cpp:115, :126 (Listeners created in adapter constructor)

@kodiai if i attach a TS package are you able to parse the packet and check for the TS stream problem?

[kodiai]

kodiai response

Yes, I can parse TS packets and check for stream issues. Please attach the TS file and I'll analyze:

(1) Packet structure and sync bytes
(2) PID mappings and continuity counters
(3) PCR/PTS/DTS timestamps
(4) Any discontinuities or malformed packets

Go ahead and attach it whenever you're ready.

[CastagnaIT]

@kodiai i attached the TS stream first segment (this is raw data, dont take look at the wrong extension)
vi1390398233_8000k_00001.ts.txt
inspect the file and try find the problem because the TSReader::Initialize and TSReader::ReadPacket is not able to find stream info

kodiai response

I ran out of steps analyzing this and wasn't able to post a complete response.

This can happen on PRs with large or complex diffs. To get a response:

• Ask a more targeted question (e.g. kodiai review LangInfo.cpp only)
• Or mention me again — the next run may complete within the step budget
